Very limited quantities available of this really clean and nice rootbeer chert. All of this rootbeer has been spalled and top graded for the best pieces of rootbeer I have ever seen. All has been lightly heat treated if it could benefit from it, or left raw if already perfect to knap. Rootbeer is semi translucent and very strong in in this bifaces. Rootbeer chert is perfect for very thin but tough blades and projectiles.
